To get the current page URL, PHP provide a superglobal variable $_SERVER.

Example 1:
<?php
if(isset($_SERVER['HTTPS'] ) && $_SERVER['HTTPS'] === 'on') {
$url = "https://";
} else {
$url = "http://";
}
// Append the host(domain name, ip) to the URL.
$url.= $_SERVER['HTTP_HOST'];
//Append the requested URL
$url. = $_SERVER['REQUEST_URI'];
echo $url;
?>The isset() function is used here to check whether HTTPS is enabled or not.

<?php
$currentURL = "http://$_SERVER['HTTP_HOST']$_SERVER['PHP_SELF']";
?>However, this will not include any query parameter or fragment identifiers.
Note that the $_SERVER[‘REQUEST_URI’] and $_SERVER[‘PHP_SELF’] variables may not be secure and can be manipulate by attackers. You should always sanitize and validate any input from these variables before using them in your code.
<?php
$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off') ? "https" : "http";
$host = $_SERVER['HTTP_HOST'];
$currentPageURL = $protocol . "://" . $host . $_SERVER['REQUEST_URI'];
echo $currentPageURL;
